All console_init_r() does is to search for devices which can be used
for STDIN/STDOUT/STDERR (whether in the environment or the device list),
call console_setfile() and then print out the list of devices found.
console_setfile() actually calls the device start routines.  The actual
registration of the devices happens in device_init() which is called
before console_init_r().

So I see no reason why moving console_init_r() would have any effect.

Did I write that I doubt anything?  No.  I just asked for some
clarification because it wasn't clear to me from the very abbreviated
descriptions on the Custodian page just exactly what is within the
purview of a custodian.
